Abstract (en)

[origin: EP3998665A1] Disclosed is a lithium metal secondary battery including: an electrode assembly including a negative electrode, a positive electrode and a separator between the negative electrode and the positive electrode; a non-aqueous electrolyte with which the electrode assembly is impregnated; and a battery casing in which the electrode assembly and the non-aqueous electrolyte are received, wherein the negative electrode includes a negative electrode current collector and a lithium metal layer formed on at least one surface of the negative electrode current collector, and the charge/discharge condition of the lithium metal secondary battery is controlled in such a manner that the battery is charged under a pressurized state with a constant pressure of 3-300 psi and discharged under a pressurized state with a constant pressure lower than the pressure applied to the pressurized state during charge.
